did he cum in me?

hey i need help like asap. i’m 16 my boyfriend is 17 turning 18 in september.

we’ve been dating for 8 months and we’ve had sex 2 times before this but about a week ago we had sex. we used a condom. right as we got into like he had barely put it in he had to grab his phone and he looked down and me and there was like cloudy white stuff coming out of my vagina. he asked if i came and i said i hadn’t yet. i thought maybe i was just wet? i’m not sure if he came in me. the condom wasn’t broken at all.
